I have a configuration where we want to use SpeedFusion to bond multiple WAN connections. One is a cellular connection and the other two are 802.11 radio links - I don’t think this matters for the question though. So I have the two WAN connections (802.11 radios) as priority one and the cellular connection as priority two as a backup in case both radios fail.
Once the SpeedFusion bond is established things seems to work mostly as I expected. If either radio link fails the bond continues with the other. if the radio link is reconnects it rejoins the bond.
When both radios fail the bond will then use the cellular connection. Then if one or both radio links reconnects it rejoins the bond.
The problem I see is if we lose the cellular connection and both radios fail, then SpeedFusion will fail and the bond won’t re-establish unless all three of the links can be created again. SeedFusion requires all of the WAN connections be available initially to establish the bond.
Does that sound right? How can we create a mobile configuration to leverage multiple WAN connections without having to require all of them initially?
